The Lepanto mine in Luzon, Philippines, is one of the classic “high-sulfidation” type copper–gold deposits (cf. Arribas, 1995).Stable isotope (e.g., Rye, 1993) and mineral chemistry (e.g., Henley and Berger, 2012) along with geologic data have established that such deposits are fossil fumarole–solfatara systems associated with A Copper Flotation Flowsheet. Because the copper in this type of ore usually assays only plus or minus 1% copper, the porphyry copper operations must be relatively large in order to be commercial.

Copper Concentrate an overview ScienceDirect Topics

Flotation is commonly used to concentrate copper sulfide minerals, such as chalcopyrite (CuFeS 2). In this example, the production of a copper concentrate is investigated. After mineralogical examination, we decided to divide the ore into four species for characterization: Cp (100% CuFeS 2 ), CpPy (95% CuFeS 2 5% FeS 2 ), PyAs (70% The Lepanto mine in Luzon, Philippines, is one of the classic “high-sulfidation” type copper–gold deposits (cf.
